Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? Can I drink milk from my girlfriend's breasts?Doctor's answer:
Breast discharge issues can be physiological or pathological. Physiological discharge occurs after weaning, where some milky fluid may still be secreted within six months. However, if there is still fluid after more than a year of weaning, pathological causes should be considered. Many diseases can cause nipple discharge, such as pituitary tumors, which can lead to elevated prolactin levels, duct hyperplasia, and the secretion of milky fluid. There is also postmenopausal galactorrhea. If prolactin levels are high in the blood, it may indicate hyperprolactinemia, and some cases may involve pituitary tumors. In some cases, small tumors may not be detectable, often requiring radiation treatment. Some discharges are not milky white; they may be clear, or there may be tumors or even cancer within the ducts. When tumors are present, the fluid is often coffee-colored or bloody. Thus, the characteristics of the discharge can vary—clear, white, yellow, brown, coffee-colored, or bloody—indicating different diseases and stages, which helps determine whether the discharge is physiological or pathological.
